US 3,976,204 A · Mechanical handling apparatus

Abstract

A mechanical handling device comprises a carriage reciprocable between a loading station and an unloading station, stationary and movable grip members on the carriage, each including two independent grip faces so arranged that there are two pairs of grip faces with each pair comprising a stationary and a movable face, and an actuator for moving the movable grip member to grip a workpiece by either one of the pairs of faces. The movable grip member may include a rotatable shaft having two arms extending in opposite directions with a jaw at the end of each arm, and the fixed grip member comprise a bar between the jaws so that rotation of the shaft in either direction brings one of the pairs of gripping faces into operation. The device is particularly applicable to the loading and unloading of billets in relation to a circular rotary hearth furnace.

Dependent claims

A mechanical handling device comprising:

a fixed framework,
a carriage mounted for linear reciprocatory movement upon said framework between a loading station and an unloading station,
a support tube mounted upon said carriage,
a stationary grip member mounted on the support tube at one end thereof, and two independent grip faces provided on said stationary grip member,
a shaft rotatably mounted within said support tube,
a movable grip member mounted on said shaft, the movable grip member having two independent grip faces so that there are two pairs of cooperating grip faces with a stationary grip face and a movable grip face in each pair,
actuating means for effecting angular movement of the shaft relative to the support tube for bringing either one of said pairs of grip faces into operation while the other pair of grip faces is non-operative.
